Wiring
Wire this device in accordance with applicable national and
local codes, ordinances, and regulations.
Notes
•
Refer to the Signature loop controller installation sheet for
SLC wiring specifications for additional details.
•
All wiring is power-limited and supervised.
•
A test resistor is supplied with the SIGA-CT1 to prevent
trouble signals on unused circuits during installation.
When connecting field wires, remove the test resistors and
install a UL/ULC Listed 47 kΩ EOLR at the end of the
circuit.
To wire the module:
1.
Verify that all field wiring is free of opens, shorts, and
ground faults.
2.
Strip 1/4 in. (about 6 mm) from the ends of all wires that
connect to the terminal block of the module.
When stripping wire ends, exposing more wire may cause
a ground fault; exposing less wire may result in a faulty
connection.
3.
Make all wiring connections as shown in Figure 2.
